12

Robert Hooke

First to observe and describe cells in 1665

13

Anton van Leeuwenhoek

Made own microscopes, identified cells in pond water, blood, semen, ground over 500 lenses, 9 known to exist

14

Matthias Schleiden and Theodore Schwann

developed cell theory

15

Cell Theory

1. Cells are the fundamental units of structure
2. Also fundamental units of function
3. All cells come from pre-existing cells
4. Cells contain genetic information

16

Prokaryotic vs Eukaryotic

Prokaryotic are 10 X smaller
Prokaryotic are less complex
Eukaryotic have membrane-bound organelles

23

Hypotheses
